Postgres gem не будет установлен на 12.10

Я пытаюсь заставить Ruby on Rails работать на моем компьютере, но гем pg не работает. Я нашел много других вопросов о том, что вам просто нужно использовать пакет libpq-dev из apt, и это должно исправить это, но он все еще говорит, что не может найти библиотеку.
